Mega-Espeon

Mega Espeon (Espeonite)
Typing: Psychic ------> Psychic
Abilities: Magic Bounce/Synchronize ------> Mind Reader (It has the combined effects of Frisk and Anticipation)
Stats: 65/65/60/130/95/110 ------> 65/65/80/165/115/135
New Moves: Aura Sphere, Heat Wave

Description

Mega-Espeon is meant to be a fast-yet-hard-special-hitter, with tons of utility thanks to its brand new ability Mind Reader. Since the Dex entry says that "it uses the fine hair that covers its body to sense air currents and predict its enemy's actions", I've decided to make it capable of doing something as similar as possible to the description: so, everytime Mega-Espeon comes in, the opponent's item would be revealed, as well as possible supereffective moves against Mega-Espeon itself. With a good boost to both Speed and SpAtk, and the addiction of Aura Sphere (Espeon is the Psychic Eeveelution: its aura is surely strong and capable of hit hard) and Heat Wave (don't forget Espeon is the Sun Pokemon, and that tons of Psychic types already know this), Mega Espeon is also no longer walled by Steel types.

THREATS
With all those boosts, Mega-Espeon is still uncapable of tanking Knock Off and Sucker Punch at all, so nearly any Dark type will be a problem for it: besides there are some SpDef wall capable of taking hits very good - for example Heatran is only 3HKOed by Aura Sphere.

Mega Umbreon (Umbreonite)
Typing: Dark ------> Dark
Abilities: Inner Focus/Synchronize ------> Synchronize
Stats: 95/65/110/60/130/65 ------> 95/90/135/60/150/95
New Moves: Knock Off

Description

Since Umbreon is already a great an A.A.F (Annoying As Fuck) Pokemon, I definitely don't see why change it too much. Same type and same ability, this time I think the stats are the most important thing to analyze: both of the defenses boosted, a good buff for attack too (and also the addiction of the infamous Knock Off to become even more annoying), and mostly a + 30 in speed. This last one is the brand new weapon of Mega-Umbreon: not all the pokemon who has access to Taunt are this fast (Terrakion, for example, is - but you won't surely stay in on a Terrakion with a Dark-type, so...), so now Mega-Umbreon is not only a slow and amazing wall, but it can also cripples the opponent's walls by nullifying their satus moves.

THREATS
Mega-Umbreon, as well as its normal form, has no viable attacking moves except for STABbed ones: this means that every Fairy or Fighting type would still be a threat to it.

Mega Jumpluff (Jumpluffite)
Typing: Grass/Flying ------> Grass/Flying
Abilities: Chlorophyll/Infiltrator/Leaf Guard ------> Infiltrator
Stats: 75/55/70/55/95/110 ------> 75/80/70/55/120/160
New Moves: Spore, Tail Wind

Description

Mega-Jumpluff got an amazing speed buff that makes it the second fastest pokemon alongside with Ninjask: it is also a little bulkier on the special side, and a little stronger on the physical offensive side (even if it doesn't matter too much). What's very good is its brand new speedy-Infiltrator-Spore, which can't be countered by Taunt users (if not Prankster ones, or Deoxys-Speed), and the always useful Tailwind, to also make its team fellows way more faster than the normal.

THREATS
Mega-Jumpluff didn't take any buff for what concerne its physical defense, and 75 HP + 70 Def stats aren't surely too hard to beat down (also counting that it has to rely only on Synthesis for gaining back HP).
